World of Optical Illusion

 

Your eyes are incredible organs. Did you know that if you have blue eyes, you share an ancestor with everyone else on the planet? Blue eyes are the result of a genetic mutation that appeared more than 6,000 years ago. Originally, all humans had brown eyes.

Optical illusions come in a variety of shapes and sizes, and we can't get enough of them. Many optical illusions reveal fascinating secrets about how our vision and brains work, as well as how we perceive color and light, while others are simply perplexing.

They're popular on social media right now, but optical illusions are nothing new. Optical illusions have been delighting and perplexing people for centuries and in many different cultures.

There are several types of optical illusions, and the majority of them fall into one of four categories. The first are physiological optical illusions. These are the 'true' optical illusions: images that cause us to misinterpret them, such as a still image that appears to be moving or an image that appears to be a specific color when it isn't. These are caused by physiological factors in how our eyes and brains interpret things like brightness, angles, and movement.

For centuries, people have been fascinated by optical illusions. Plato and other Greek philosophers described them as tricks played on us by our senses and minds. W.E. Hill, a famous cartoonist, embraced the phenomenon of optical illusions by skillfully sketching a picture that was simultaneously two images by the nineteenth century. Your perception determined the figure you saw. It could have been a young girl or an elderly woman.
